THE WORLD CHAMPION
The E2 is ESORO’s first electric vehicle. With its consumption from the mains of 5.5 kWh/100 km, this two-seater is the world’s most efficient car. It is able to fully cover its energy demand for 10,000 km/year with only 4.5sq m of stationary photovoltaic solar cells.
The E2 won the following races and competitive events:
- World champion (Tour de Sol) 1988 / 1989 / 1990 / 1991
- European champion 1990 / 1991
- Best lightweight electric-driven car in 1989, suitable for everyday use
- Winner in the Austro Solar 1989
- Winner in the Grand Prix E 1990
With its drag coefficient of 0.165, the vehicle has the world’s lowest aerodynamic drag for a two-seater and is also the first lightweight electric-driven car with ASR/ABS.
